Thus it is that Allah seals the hearts of those who deny the truth. 101 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 So he cast his staff; and behold, it was a serpent manifest. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
